Which rechargeable battery to choose?
August 12, 2009
Lately I've been a bit more careful about how I spend my money on my robotics projects (wasn’t able to get a summer job this year) and I have notices one big problem: batteries!
My first robot takes 12 AA! And they dont last all that long before you start noticing differences in performance.
My second one takes a 9V and if you know a bit about batteries you'll know that is a really bad battery to use.
So I would like to replace that 9V with a rechargeable battery, something that gives out 9V to ~15V and wont break the bank.
So any suggestions would help loads!
